The first pigeon I found.
It's on the cabaret's roof, you can get it after killing Faustin, just jump down the roof as shown in the video.

A standard game against 6 comps on the money map 'Fastest Map Ever'.
This shows the basic strategy to win against comps, you basically have to block the entrance to your main and build some defense while you gather enough resources to kill the comps. Then just keep making units till you win the game.
Of course, this strategy only works against computers and any decent player will kill you in 5 minutes with a simple drop if you do this.
And remember: Money Maps are just for fun. If you want a real challenge, play a REAL map. (:
